According to a Riverton City press release, the mayors of Riverton, Herriman, West Jordan and Copperton are opposed to the possibility of the "Olympia" master-planned community that could come to the south-west part of the valley.

A joint statement by the mayors criticizes the 931 acre development plan (located approximately from 6300-8500 W and 12400-13100 S) for its high density.

"The sheer number of units in the development is nothing short of overwhelming. With a proposed 8,765 units on 931 acres. It is estimated that this would add an additional 30,000+ residents to the southwest part of the valley; essentially adding another city approaching the size of Herriman or Riverton, but in a tenth of the land area," read the statement.

The statement also raised concerns over how such a development would affect surrounding cities' infrastructure, transportation and open space.

The statement was addressed to the Salt Lake County Council, which will be deciding during its June 5 council meeting whether or not to rezone the proposed land area from A-2, an agricultural zone, to P-C, a planned community zone.
